Jason's world of constant lying is established: he lies to avoid gym class, lies to his parents, lies about homework. His best friend Kaylee supports him. His parents are frustrated but tolerant. Final lie: claiming he wrote an essay when he hasn't, forcing him to write "Big Fat Liar" in desperation.

Collapse
All is lost: Wolf captures Jason and Kaylee, locks them in a prop room on the Universal Studios tour, and has them sent back to Michigan. Jason's parents know he lied and ran away. The movie premiere proceeds without consequence for Wolf. Jason's quest for truth seems dead, as does his credibility.
